Diffuser PEARLCOMB

Tube type membrane

Superfine air bubble diffuserTube type membrane

The high oxygen transfer efficiency is acquired by generating ultrafine bubble. Since it can be installed freely according to the shape of the tank, the place of installation is very flexible. Multiple types of membrane material are available according to the purpose of use of the waste water.

Features of the tube type membrane

High oxygen transfer efficiency, low pressure loss

High oxygen transfer efficiency, low pressure loss
Since ultrafine bubbles are supplied into the liquid from a lot of pores in the diffuser plate, high oxygen transfer efficiency is acquired. In addition, low pressure loss (air-flow resistance) is realized with the product by using flexible material.

It is possible to change from porous diffuser plates.

It is possible to change from porous diffuser plates.
It is possible to use the existing equipment as-is because it is possible to replace the existing diffuser plates.

Energy saving

Energy saving
Our membrane diffuser realizes high oxygen transfer efficiency and low pressure loss by generating ultrafine bubbles, which enables to reduce the amount of air blow by 30% from the amount before installation.

Applicable to various waste water treatment

Applicable to various waste water treatment
The membrane material can be selected according to the purpose of use of the waste water.

Purpose of use

Diffusers of sewage treatment plants and human waste treatment plants, diffusers for industrial waste water treatment, diffusers for waste water from agricultural communes, diffusers for livestock waste water treatment, diffusers for small combined septic tanks, oxygen supply to culture ponds, etc.
